Student Builds Home Brew Supercomputer

When Andrew Broadhurst found the lab computers were not quite to his like in terms of power and architecture when simulating the dispersion of volcano ejections, he built one himself. The finished computer is equipped with one NVIDIA GT 730 GUP and two Intel Xeno Phi 31S1P coprocessor cards. It enables a combined peak performance of 3TFLOPS under a hybrid programming model. As Andrew explains in detail, designing a high performance computer is a non-trivial process of carefully juggling of power, cooling, memory and bus performance. For more about the system, see his report on steps to build this computer, and also the rationale for the design and choice of parts.
